Document - User Guide

Envisat and ERS Missions Data Access Guide

The purpose of this document is to help users identify the various types of data that are available from the ENVISAT, ERS-1 and ERS-2 Earth observing satellites, the kind of applications that the data may be used for and, importantly, the practical procedures required for access - including user registration and then search, selection and retrieval or ordering of the data of interest.

Activity - Projects

Auroral Electrojet and auroral Boundaries estimated from Swarm observations

In the Swarm-AEBS project, a set of new Swarm data products that characterise the auroral electrojets and auroral oval boundaries will be derived from Swarm magnetic field measurements.

Activity - Quality

REAPER

The REAPER (REprocessing of Altimeter Products for ERS) project covers both the ERS-1 and the ERS-2 altimetry missions. The project aims to support and maintain data quality.

Mission - Heritage Missions

ERS

The ERS programme was composed of two missions, ERS-1 and ERS-2, which together observed the Earth for 20 years, from 1991 to 2011.

Mission - Earth Explorers

Swarm

Swarm is dedicated to creating a highly detailed survey of Earth’s geomagnetic field and its temporal evolution as well as the electric field in the atmosphere using a constellation of three identical satellites.

Data - EO Sign In Authentication (Open)

ERS-1/2 SAR IM Single Look Complex L1 [SAR_IMS_1P]

The SAR SLC product is a single look complex acquired in Image Mode. It is a digital image, with slant range and phase preserved, generated from raw SAR data using up-to-date auxiliary parameters. The products are intended for use in SAR quality assessment, calibration and interferometric applications. A minimum number of corrections and interpolations are performed on the data. Absolute calibration parameters (when available) are provided in the product annotation. Product characteristics: Pixel size: 8 m (range - across track) x 4 m (azimuth - along track – varying slightly depending on acquisition Pulse Repetition Frequency) Scene area: 100 km (range) x at least 102.5 km (azimuth) Scene size: 5000 samples (range) x at least 30000 lines (azimuth) Pixel depth: 32 bits signed integer (16 bits I, 16 bits Q) Total product volume: 575 MB Projection: Slant range- Number of looks: 1.

Data - Data Service Request (Restrained)

ERS-1/2 SAR IM L0 [SAR_IM__0P]

This SAR Level 0 product is acquired in Image Mode. The products consist of the SAR telemetry data and are supplied as standard scenes. It also contains all the required auxiliary data necessary for data processing. The product serves two main purposes: For testing ERS SAR processors independently from the HDDR system For users interested in full SAR data processing. Product characteristics: Scene area: 100 km (range - across track) x full segment length (azimuth - along track) Scene size: 5616 samples (range) x full segment length (azimuth) Pixel depth: 10 bits signed integer (5 bits I, 5 bits Q) Projection: Slant range.

ERS-1/2 SAR IM Precision L1 [SAR_IMP_1P]

The SAR Precision product is a multi-look (speckle-reduced), ground range image acquired in Image Mode. This product type is most applicable to users interested in remote sensing applications, but is also suitable for calibration purposes. The products are calibrated and corrected for the SAR antenna pattern and range-spreading loss. Radar backscatter can be derived from the products for geophysical modelling, but no correction is applied for terrain-induced radiometric effects. The images are not geocoded, and terrain distortion (foreshortening and layover) has not been removed. The numbering sequence relates to the satellite position and therefore differs between Ascending and Descending scenes. Product characteristics: Pixel size: 12.5 m (range - across track) x 12.5 m (azimuth - along track) Scene area: 100 km (range) x at least 102.5 km (azimuth) Scene size: 8000 pixels range x at least 8200 lines (azimuth) Pixel depth: 16 bits unsigned integer Total product volume: 125 MB Projection: Ground-range Number of looks: 3.
